Iowa visits: Yes, recent visit with strategists and media. Also, August 2013 speech to conservative Christians in state where he won the 2012 caucuses. Illness kept him away from an event last April by Faith and Freedom Coalition. Screened his new Christmas movie in Iowa in November.

New Hampshire: Yes, March speech to Northeast Republican Leadership Conference marked his return to a state where he performed weakly in 2012 campaign.

South Carolina: Yes. Campaigned in April 2013 for former Gov. Mark Sanford's opponent, Curtis Bostic, in a GOP House runoff race. Sanford won.

Meet the money: 2012 shoestring campaign was largely fueled by a super political action committee to which Republican donor Foster Friess gave more than $2 million. Santorum bunked at supporters' homes on occasion.

Networking: Opened 2014 with Texas speech to conservative think tank and followed with speech to Conservative Political Action Conference criticizing GOP establishment. Speeches around the country. In 2013, previewed "The Christmas Candle," a film made by his Christian-themed movie company, for conservative religious leaders at Values Voter conference in Washington. Screened it for other like-minded groups.

Hog the TV: Yes, largely in pursuit of plugging his Christmas movie. "The Colbert Report," Fox News, MSNBC and more. Radio, too. Teamed up with Democrat Howard Dean as sparring partners for debates on the air and with audiences. Occasional Sunday news shows.

Do something: Making Christian-themed, family-friendly movies at the moment; has record from Senate days.

Take a stand: Lately, against "dangerous" U.N. Disabilities Treaty. Social conservative activism goes way back. Focus on blue-collar economic opportunity.

Baggage: Overshadowed by newer conservative figures, conceivably out-popes the pope on some social issues. 2012 positions included opposition to abortion even in cases of rape or incest and support for right of states to ban contraception and gay marriage. Deflection: Being overshadowed means being an underdog, and he can thrive at that. Feisty 2012 campaign became the biggest threat to Romney's march to the nomination at one point.

Shadow campaign: Keeps in touch with chief supporters of his winning 2012 Iowa caucus campaign, giving him a leg up on a campaign organization in the state.

Social media: Active on Twitter and Facebook, where he relentlessly plugs his new Christmas movie, gives away tickets and goes after the health law.
